GUI

A GUI (pronounced 'goo-ee'), or (G)raphical (U)ser (I)nterface, is the general term describing a method in which input and output elements in a computer system are abstraced into objects on the computer's video display device. The GUI was popularized by Apple Computer's Macintosh and has seen it's most versatile implementation on the World Wide Web.

In the the dark mists of time, that is the pre Windows 3.x days when DOS ruled supreme, so-called PC (and usually self-proclaimed) power users would denigrate Mac users choice of machine by calling GUIs a W.I.M.Pinterface.
